Calculated signal-noise ratio of the combination of a P-I-N photodiode and a distributed amplifier with frequency dependent characteristic impedances

The distributed amplifier gives a novel approach to a high speed photo-detecting circuit. This paper presents a combination of a p-i-n diode and a distributed amplifier with frequency dependent characteristic impedances. A 14.3 dB improvement in signal-to-noise ratio for this configuration is predicted at a bandwidth of 40 GHz over a conventional grounded-source amplifier combination.
